Methyl cellulose (Dow A4M),  2% to 5% in water (Wagner method)	• Brush onto (matte) polyester film  • Mist repair paper (except Berlin) • Drop repair paper onto adhesive • Let air dry	• May pre-swell in humidity  chamber or damp pack • 1:1 water/alcohol (low-moisture)
Isinglass 10% in water	• Brush onto (matte) polyester film  • Drop repair sheet (fish intestine, goldbeaters skin or leather) onto adhesive • Let air dry	• 1:1 water/alcohol (low-moisture)
Hydroxypropyl cellulose  (Klucel-G), 2-5% in water	• Brush onto (matte) polyester film  • Mist repair paper (except Berlin) • Drop repair paper onto adhesive • Let air dry	• May pre-swell in solvent chamber  or damp pack • Alcohol; for very thin tissues, reactivate with 2% Klucel-G in alcohol to avoid rinsing out the coating
	• Berlin tissue: place dry paper on film  • Foam adhesive through window screen • Remove screen • Let air dry
Lascaux 498HV, thinned 2:1  up to to 4:1, water:Lascaux	• Brush thinned adhesive onto silicone  release film or mat • Continue to brush until stops beading up (~2 minutes) • Mist repair paper • Drop repair paper onto adhesive • Let air dry	• May pre-swell in solvent chamber  or damp pack • Alcohol
		• Heat
Lascaux 498HV, straight  (thicker repair papers)	• Squeegee adhesive through silkscreen onto  silicone release film; rinse • Mist repair paper and adhesive • Drop repair paper onto adhesive • Let air dry	• May pre-swell in solvent chamber  or damp pack • Alcohol
		• Heat

ADHESIVES	PREPARATION GUIDELINES	REACTIVATION METHOD
Lascaux 498HV and 360HV  mix	• Prepare as for Lascaux 498HV thinned or  straight when you want more elasticity or flexibility.	• May pre-swell in solvent chamber  or damp pack • Alcohol
		• Heat
Lascaux 360HV, straight  (Sheesley method)	• Pipe adhesive onto repair paper, distribute  adhesive between two sheets of silicone release mylar; remove top sheet • Let air dry with a tray to cover so no dust contamination	• Tacky at room temperature  • Alcohol

		• Heat
BEVA 371 film (1-mil)	• Heat-seal directly onto repair paper	• Heat
BEVA 371 solution	• Spray the BEVA solution from an aerosol	• Heat
	• Coat repair paper with a solution of BEVA  film and 1 or 2% petroleum benzine / VM&P naphtha
“Modified” LC Heat-Set  (Rhoplex AC 73 and Rhoplex AC 234)	• Mix adhesives (1:1) and thin 1:1 with  deionized water • Brush thinned adhesive (1:1 mix with deionized water) onto silicone release film • Continue to brush until stops beading up • Mist repair paper • Drop repair paper onto adhesive • Let air dry	• May pre-swell in solvent chamber  or damp pack • Alcohol
